Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a steel material for a window,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a steel girder beam for a window, and more particularly to a girder beam using a steel material capable of maintaining a stable structure by using a steel material.

It is a member installed on the door frame or the upper part of the window frame to support the mate- rial such as the bricks or the like installed on the window or door of the wall, and to distribute the load from the upper part to the left and right walls. Arch bricks are used in masonry buildings, but reinforced concrete grooves are installed in areas where the upper straight pressures are large. Sections of 20 cm or more are installed on the lower bricks or blocks at end parts.

On the other hand, the conventional lavas are made of reinforced concrete using cement as the main raw material or manufactured by cement extrusion molding method, so that they are heavy in weight and are vulnerable to shock, which causes a problem of damage during transportation. In addition, since the extrusion molded product of the factory has many variables such as the quality of the raw material and the strength in the curing process, the product of 2.0 m or more has a disadvantage in that cracking due to breakage or deflection occurs when the anchor is fixed.

In addition, electric wiring such as an electric switch pipeline is often passed to the end of the tongue. Since the conventional tongue is constructed such that the electric wiring can not penetrate, a part of the electric wiring should be cut off. In this way, when the lid portion is partially cut, not only the structural stability of the lid is weakened but also the working time is increased by adding a process of cutting the lid portion.

In addition, even when a steel strip is manufactured using a steel material in the past, it is horizontally installed, and deflection easily occurs due to an upper load, thereby causing structural stability to deteriorate.

The present invention provides a steel member hollow beam for a window having a structure capable of increasing the structural stability by using a steel material and achieving an improved support strength against an upper load even with a small weight.

In addition, the present invention provides a steel member hollow beam for a window which can improve structural stability in consideration of deflection after construction.

A lower support bar having at least two or more curved projections upwardly protruding upwardly from the steel frame for a window according to the present invention and spaced apart in a horizontal direction; An upper support bar having a curvature formed so as to protrude upward and spaced apart from an upper portion of the lower support bar; And a truss member connecting between the lower support bar and the upper support bar and arranged at regular intervals to partition the brick or block so as to be received between the lower support bar and the upper support bar.

The truss member may further include: a first connecting bar connecting the lower supporting bars; And a second connection bar connecting the outermost support bars on both side surfaces of the lower support bars and the upper support bar.

In addition, the first connection bars and the second connection bars on both sides may be integrally formed or a triangle having a shape in which the upper ends of the second connection bars are spaced apart.

The truss member may further include a third connecting bar connecting the upper supporting bars when the upper supporting bars are two or more.

Also, the first connection bar, the second connection bars on both sides, and the third connection bar may be integrally formed in a rectangular or trapezoidal shape.

Further, the truss member may be formed in a plate-like shape, and a groove or hole-shaped bar accommodating portion for accommodating the lower support bar and the upper support bar may be formed.

The bar receiving portion of the truss member may be welded to the lower support bar and the upper support bar.

Further, a male screw is formed on the outer peripheral surface of the lower support bar and the upper support bar, and the truss member can fix the lower support bar and the upper support bar inserted in the bar accommodating portion by using a nut.

Further, the truss member may be any one of a triangle, a square, and a polygon.

Further, the truss member may be formed with an incision portion at least a part of which is cut at the center.

Further, the upper support bar is formed only in a section where the truss member is provided, and the length of the upper support bar is longer than the length of the section where the truss member is provided, so that the upper support bar can be further protruded to the outside of the outermost truss member .

The lower support bar of the section where the truss member is not provided is provided with a lower connection bar connecting the lower support bars, and the lower connection bar is fixed to the lower support bar at a position lower than the height of the lower support bar .

Further, the lower support bar, the upper support bar, and the truss member may be made of a reinforcing bar or a steel wire.
